-Passage (pelvis/birth canal) -Passenger (fetus) -Power (physiologic force of labor) -Position (maternal positioning in labor) -Psyche
162
If components of the 5 P's of labor are altered, the outcome of labor can be adversely affected, leading to:

162
Passage
*route that the baby must use when leaving the uterus, arriving at the external perineal area for birth -includes maternal pelvis and soft tissues

164
Android Shape
*occurs in 20% -heart shaped, norm male pelvis -diameter is kinda narrowed-->difficult fetal passage
165
Anthropoid shape
*25% of females (HARDEST TO GIVE BIRTH WITH) -oval with longer anteroposterior diameter -may be difficult passage except when baby in an occiput posterior position
165
Platypelloid
*5% of females (COMPACT) -oval or flat -might be difficult for bby to rotate to match shape of pelvis at appropriate diameter
166

1. cephalic 2. breech 3. shoulder
175
vertex cephalic
parietal bones/space between fontanels presents first
176
brow cephalic

177
face cephalic
poorly flexed-->face presents first
178
mentum cephalic
chin presents first
179
complete breech
-thighs tightly flexed -criss-cross -cant be vag delivery
180
frank breech
fetal hips flexed, legs extended and resting on chest
181
footling breech
1+ feet point down and deliver before body *MOST DIFFICULT OF BREECHES
182
shoulder presentation
-shoulder, scapula, hand, or elbow presents first -lying horizontal in pelvis REQUIRES: -early dx/intervention -fetus may turn before delivery -C/S is almost ALWAYS needed (Mom may have distorted shape)
183
